Bank of America has reopened its European Momentum Conviction Indicator crash signal after 30 days. The bank characterizes the current episode as more consistent with aftershock fragility than with a high-probability, multi-wave collapse in 12-month price momentum. The signal reopened near the trough in 12-month momentum and following the bulk of deterioration in the indicator's inputs. Recent analyst revision data and fund flows in Europe show a mixed picture, with weak 1-month revision ratios and meaningful passive inflows to Stoxx 600 constituents despite overall outflows from Europe-focused funds.

Key Points

  • Bank of America reopened its European Momentum Conviction Indicator crash signal after 30 days, characterizing the episode as aftershock fragility rather than a likely multi-wave momentum crash.
  • July analyst revision ratios showed weakness: sales revision ratio at 1.07 and EPS revision ratio at 0.98 (net-downgrade territory); dividends rose slightly to 1.50 while buybacks fell to 1.51. Inventories and capex strengthened to 2.13 and 2.05 respectively.
  • Fund flows were mixed: Europe-focused equity funds recorded $2.28 billion of outflows last week (active outflows $0.95 billion, passive outflows $1.33 billion), while EURO STOXX 600 constituents saw $3.05 billion of inflows driven by $3.24 billion of passive inflows amid $0.19 billion of active outflows. Cheap value stocks outperformed expensive value stocks by 17% in July, broadly across sectors and countries.

Bank of America has reopened the crash signal on its European Momentum Conviction Indicator after a 30-day interval, according to the bank's report. The firm notes that the current episode appears to fit a pattern of aftershock fragility rather than signalling a high-probability, multi-wave crash in 12-month price momentum.

The bank highlights that the reopening occurred close to the trough in 12-month price momentum and after most of the deterioration in the underlying inputs had already taken place. In searching its archives for precedent, Bank of America identified only three comparable cases of similar reopenings following an initial momentum crash: March 1999, November 2000, and February 2021.


Monthly revision metrics for July showed a weakening trend in short-term analyst revisions. Sales revision ratios slipped to 1.07, while earnings-per-share revision ratios moved down to 0.98, placing EPS revisions back into net-downgrade territory. Dividends per share ticked up marginally to 1.50, while buybacks fell to 1.51.

Other corporate metrics were mixed: inventories strengthened to 2.13 and capital expenditure revisions rose to 2.05. Net debt revisions declined to 1.23, and price target revisions reached 2.34.


Fund flow data for the most recent week show Europe-focused equity funds recorded total outflows of $2.28 billion. Active funds accounted for $0.95 billion of those outflows, while passive funds registered $1.33 billion in outflows.

At the same time, constituents of the EURO STOXX 600 index drew $3.05 billion of inflows overall. Those inflows were driven by passive allocations, which contributed $3.24 billion, compared with $0.19 billion of outflows from active funds.

July's performance among value segments was notable: cheap value stocks outperformed expensive value stocks by 17% in the month. Bank of America notes this represented the fifth-strongest monthly return on record and the strongest since January 2022. The outperformance was broad-based, occurring across 18 of 20 sectors and in all eight countries included in the bank's analysis.

Collectively, the reopened momentum signal, coupled with the revision and flow dynamics, presents a nuanced landscape for European equities. The bank's framing of the episode as aftershock fragility suggests the immediate risk may be concentrated around momentum metrics that recently hit troughs rather than signalling an extended multi-wave deterioration.

Risks

  • Momentum metrics are fragile - the reopened signal occurred near the trough in 12-month price momentum and after most deterioration in inputs, indicating vulnerability in momentum-driven segments of equities.
  • Analyst revisions show short-term weakening - EPS revisions returned to net-downgrade territory (0.98) and sales revisions fell to 1.07, which could pressure sectors sensitive to earnings momentum.
  • Divergent fund flows - simultaneous outflows from Europe-focused funds and passive inflows into Stoxx 600 constituents create uncertainty for active managers and could affect liquidity patterns across equity sectors.
